McCavour/McCaver/McAver Family

Can someone help me track down the family of Hugh McCavour???I don't have much information on him.I have here that he was born in Kilkeel, Down County and immigrated to Canada in 1829.I don't have a birth date.He married a Jane Floyd born in Ireland 1789 and died in Canada in 1857.They had a son also named Hugh McCavour born in Ireland 1820, died in Canada 1912, married Susan Moore.This is all I have to go with...any help would be greatly appreciated.Thanks, Paula
